Alright, thanks, I'll adapt my OpenWRT patches to that.

In theory pkg-config should handle all that. I didn't want to break
anything for dnsmasq, hence didn't touch the gmp linkage, but if
libnettle.so properly links against a required libgmp.so you shouldn't
need to add it explicitly.
But I've seen too many cases where that doesn't work out in reality :\
